Windows 10: Feature update to Windows 10, version 2004 installation error 0x8007042b

JABDJB71 · Jun 18, 2020

I have attempted to upgrade one of our Win10 machines twice to Version 2004 but each attempt has failed with error '0x8007042b'. This machine is currently updated to: "2020-01 Update for Windows 10 Version 1909 for x64 based systems KB4497165". The scenario for both failed upgrade attempts was:

Download completed successfully

Installation initiates and runs for around 2 hours with multiple reboots

Installation percentage reaches around 90% and doesn't progress beyond that level for roughly 30 minutes

Message is displayed denoting that changes will be backed out

The back out successfully completes after another 20-30 minutes

The result 3+ hours later is the machine is back to the Version 1909 level

I see that there are quite a few other issues being documented with the install of Version 2004 in this forum. Is Microsoft working on fixing these installation issues or are they leaving it for the user community to resolve them on our own? It's very frustrating!!
